It looks more dangerous to continue your bets or trades after you already had several losses as it's time of more emotional impactful decisions which usually are not good ones. Though it is risky practice, it does not mean it is only time when a gambler can make bad decisions. In the other times, like after several wins or a very lucky big win, a gambler can continue betting and possibly fall into emotional bets too.
It's addictive to do more bets when you are in a win streak as emotion is positive, dopamine makes you feel happy and it's sensitive time to forget about principles, break important discipline, and it's one of most dangerous time to lose money.
